STEAM AND HYDRAULIC PUMPlNG-ENGINE.

SPECIFICATION forming part of Letters Patent No. 291,892, dated January 15, 1884.

Application filed December 26, 1882. (No model.)

To aZZ whom it may concern.:

Be it known that I, HARVEY F. GAsKILL, of Lockport, Niagara county, New York, have invented certain Improvements in Steam and Hydraulic Pumping-Engines, of which t-he following is a specification.

This invention relates more especially to pumping-engines designed for places in which there is a moderatewater-power, and in which it is sometimes necessary to supplement the water-power with steam; and its object is to provide a simple and cheap machine which can be used with water-power alone, or with steam-power alone, or with steam and water power combined. To this end I employ eertain features of construction shown in the patent granted me September 5, 1882, No. 263,694, and certain other features not shown in that patent but described hereinafter, the improvements claimed herein being a part of the same invention to which that patent pertains.

The principal elements entering into the combinations which constitute my invention are the following, viz: One or more pumps and their fittings; one or more steam-cylinders in line with the pumps, a crank-shaft set above the pumps and mounted in bearings on them; a gear-wheel, which also acts as a iiywheel, on thc crank-shaft; a beam connected to the pump and piston-rod and also to the crank-shaft; a pinion meshing with the gear; a water-motor acting'upon the pinion-shaft.

In practice thus far I have preferred to build the engine on the duplex principlethat is to say, having two pumps placed side by side, land having the gear and fly wheel between them, and having a steam-cylinder in line with each pump, and the cranks set at right angles with each other. I have also preferred to have the gear-wheel of such proportions that it alone will be a sufficient flywheel.

Tlie drawings show a machine of this character.

Figure I is a side elevation of the machine. Fig. 2 is an elevation showing the steam-piston, the pump-plunger, the crank-shaft, and the operative connections in their relative positions. Fig. 3 is aplan showing the steampiston, the pump-plunger, and the operative connections, the beam being in section.

In the drawings, OQ is a foundation, generally of masonry. O is the base-casting of the engine-frame. B is a pump; f, a pillowblock or bearing for the crank-shaft G, located on the pump; F, the gear iiy-wheel between the two pumps; D', a pinion; I', the pinionshaft, having its bearings on a backward eX- tension of the base-casting O. II is a turbine wheel. E F are bevel-gears, through which power from the water-wheel is transmitted to the pinion-shaft I', whence it is transmitted through the pinion and gea-r wheel to the crank-shaft G. I is a standard, which supports bearings for the beam-shaft j. J is a beam; g, a connecting-rod between upper end of beam and crank. There are two of these beams-one between each pump and its crank. A is a steam-cylinder in line with the pump. c is the steam-piston. b is the pump-plunger. C is a double piston-rod, connecting the piston c with cross-head d. b is the pump-rod. C are rods, and C a cross-head, connecting the pump-rod b with cross-'head d. d is a crosshead on the pump and piston-rod. D is a guide for the cross-head. c is a link connecting the cross-head with the lower end of the beam. Q and R are strut-ties connecting the steam-cylinder, the standard P, the pump, and the main bearing j'.

Vhen desired, the steam-cylinder may be disconnected, and the pumps run by waterpower alone, or the water-motor may be disconnected and the pumps run by steam-power. An additional steam-cylinder may be placed on each of the cylinders A and connected therewith, as in a compound engine. vIn this case the additional cylinders may operate on the upper ends of the beams. Then thus constructed, the steam machinery will be like my patent of September 5, 1882.

What I claim is- 1. rIhe combination of the pump, the steamcylinder in line with the pump, the watermotor, the crank-shaft having a bearing on the pump, the gear and fly wheel on the crank-shaft, and the beam, substantially as described.

2. The combination of the pump, the steam IOO Wheel 0n theshaft, the beam, the pinion, :md the l pinion-shaft having@ a, bearing on the 1o backward extension of the frame.
